Quantum Armor

Quantum Armor is the most effective Armour in IndustrialCraft 2 (see Armor Comparison). Its durability is only surpassed in Tekkit by Dark Matter, Red Matter, and Gem Armor. It uses EU charge to absorb almost 100% of damage taken, protecting the player from everything until it runs out of charge (though falling from extremely high y-values can prove fatal; falling 1514 blocks kills instant on impact). However, a Nano Saber or its much more powerful Alchemical counterparts, can drain charge much faster than weaker weapons, due to higher damage dealt. It does NOT drain Quantum Armor rapidly like it does against Nano Armor. Each piece must be charged with EU in an MFSU, HV Solar Array, or Charging Bench MK. 3. Despite the fact that it protects from all damage, some players choose to use Gem Armor instead, as Gem armor has unlimited durability and powerful offensive bonuses granted.
